I can confirm that the EIT-1 fits in a Pelican 1510 with room to spare. I posted photos in the old forum if you want to search. It also meets most (all??) carry-on requirements. I’ve taken it overseas and had no issues.

For my other two elektrons that sit right under my computer monitor, I use the Bluelounge Nest. They’re the perfect angle as they don’t interfere with the monitor view but provide a great angle to work with. (Amazon.ca)
